BURNER FOR WATER-HEATERS.

SPECIFICATION forming part of Letters Patent No. 638,143, dated November28, 1899.

Application filed December 22, 1898. Serial No. 700,020. (No model.)

To all whom it may concern:

Be it known that I, ISAAC E. REIs, a citizen of the United States,residing at the city of St. Louis, in the State ofMissouri, haveinvented certain new and useful Improvements in Burners forWater-Heaters, of which the following is a full, clear, and exactdescription, reference being bad to the accompanying drawings, formingpart of this specification.

My inventi'on relates to an improved burner for use in apparatus forheating water by the use of gas or other vapor.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I isa vertical section of my improved heater, taken on the line II, Fig. II. Fig. II is a horizontal section taken on the line II II,Fig. I. Fig. III is a top or plan view of the burner, showing the baseof a stove and parts of water-heater pipes. Fig. IV is a transversesectional view of the burner. Fig. V is a similar view to Fig. IV, thisView showing part of of the casing or housing of the burner and parts ofwater-heating pipes. Fig. VI is a longitudinal vertical sectional viewof the burner, taken on line VI VI, Fig. V.

1 represents the burner of the heater, which is made in the form of anoutside surrounding tube or pipe, preferably of rectangular form, asshown in Fig. III, and cross tubes or pipes 2, that connect the sides ofthe surrounding tube together. The lower halves of all of the tubes arepreferably made in one casting and the upper halves of all of the tubesin another casting, the two parts being fitted together, as shown inFig. IV, the surrounding tube having flanges 3, secured together byscrews 4 or otherwise, by which the two castings are united. The flangeforms the base of the stove and rests upon supportinglegs.

'The upper half of the flange 3 is provided with an upturned edge 6 atits corners to receive an outside casing or jacket 7 of the heater. Theupper half of the tubes or pipes of the burner are provided with slotsor slits, as shown, for the escape of gas, which enters through asupply-pipe 8 and a mixing-chamber 9 of usual construction, where it ismixed with oxygen.

Within the outer casing 7 is an inner casing 10, between which and theouter casing there is an air-chamber 11. The inner casing is elevatedsome distance above the burner and is preferably supported by standards12, secured to the base of the burner. By making the burner in the formof two castings, each of which contains one-half of the tubes or pipes,it is cheaply produced and is of a durable character. The cross-tubes ofthe burner, with the exception of the second and third from each end,are separated by spaces 13 for the admission of air, the second andthird tubes, respectively, from each end of the burner having no spacesbetween them, as shown at 14, Fig. VI, whereby the two castings of theburner are more firmly bound and held together.

15 represents aWater-supply pipe provided with a faucet 16, in which isa regulating plug or valve 17, so that when the faucet is opened thefiow of water can be regulated to a nicety by screwing the plug up ordown. The supply-pipe communicates with a coil 18, located within thecasing 10, and which is supported on cross-pieces 19, secured to thestandards 12. The coil extends from the supply-pipe 15 upwardly into thecasing 10, above the burner, and is then bent back and forth anddescending joins at 2 with a discharge-pipe 23, either end of which maybe used as an outlet, the other end being closed by a cap 24.

I do not herein claim the form of coils shown in connection with myimproved burner, as the same forms the subject-matter of my application,Serial No. 709,708, filed March 20, 1899.

I claim as my invention- 1. A burner for substantially the purpose setforth consisting of a surrounding tube and cross connecting-tubes formedin castings secured together, part of said cross connectingtubes beingseparated and part being joined together, substantially as described.

2. A burner for water-heaters, consisting of a surrounding tube andcross connectingthe castings are secured together and which form asupport for the Water-heater casing, 10 substantially as set forth.

ISAAC E. REIS.
